Description

The proposed device relates to means for uniform dense filling with bulk material, such as catalysts and adsorbents, cavities of chemical production apparatuses, and can be used in various industries.

Compaction of the loaded mass in the tank is necessary to increase the bulk density and, accordingly, increase the efficiency of using the volume of the filled tank.

A device for uniform loading of bulk materials [1], in which the loaded material is gravity fed to the separation cones and divided into streams that fill the volume of the loaded tank. The known device has a fairly simple design, it is not difficult to manufacture and operate, but the disadvantage of this method is the low efficiency due to insufficient uniformity of filling of the tank.

A device for the distribution of bulk material [2, 3], which contains a loading funnel with a horizontally located discharge nozzle mounted for rotation around the vertical axis of the funnel. The uniform distribution of the material during loading is facilitated by the closed end ends of the tubular nozzle and the discharge openings made in its side surface. However, the known device does not provide a seal of the loaded bulk material.

A number of devices are known [4, 5] for uniformly filling upright containers and vessels with bulk material. The design of these devices includes a loading funnel (receiving hopper), a vertical shaft mounted along the axis of the loading funnel (receiving hopper) and kinematically connected with the drive of its rotation, ring plates coaxially located along the shaft. The known device [6] also has a vertical shaft kinematically connected with the rotation drive, while the Central loading hole is located in the upper smaller base of the reflective cone. The design of this device provides a spreading disc. All of the above devices are designed to uniformly fill vertically oriented containers with the flow of the loaded bulk material in the form of a continuous rain stream. This ensures a uniform and fairly dense container load. The disadvantages of the above structures include insufficient compaction of the loaded material and a rather narrow scope - use only for vertically standing vessels.

A fairly complex structure has the known device apparatus for filling a container with a bulk product or bulk solid [7]. This unit, in addition to the spreading plates, is equipped with a so-called diaphragm. The diaphragm provides a control of the throughput at the speed of rotation of the shaft with plates attached to it for spreading particles. The advantage of this device is to ensure uniform filling of containers of various configurations, the problem of clogging the spreading plates with a filled substance is also solved. The disadvantages of the prototype is the complexity of its design, high requirements for the accuracy of manufacturing of its parts and significant metal consumption.

A device [8, 9] is known for loading catalysts and adsorbents, which provides an increase in the characteristics of the obtained bulk layer of catalyst or adsorbent in uniformity and density by reducing vibration of parts of the device. It is equipped with a hollow rotor with slots formed by plates that are attached to the lower rotating element. The disadvantages of the device include the fact that the slots formed by the plates have the same size along the entire length, as a result of which it is impossible to control the density and uniformity of the loaded material.

Closest to the claimed model is a device for compacted loading of bulk materials [10, prototype]. In contrast to the known analogues, the slots are made expanding from the axis of rotation to the periphery and are mounted with the possibility of displacements in the direction of the longitudinal edges of the bottom of the rotor. Control over the speed of rotation of the device is carried out using a sensor mounted at the level of the rotor flange. The disadvantage of the prototype is a decrease in the performance of the boot device during the technological cycle. As the hollow rotor is filled with bulk material, its rotation speed decreases, which in turn negatively affects the quality of the bulk layer.

The objective of the proposed utility model is to eliminate the disadvantages of the prototype device, increase the operational characteristics of the loading machine and its efficiency in production conditions.

The problem is solved due to the fact that the device for the compacted loading of bulk materials into technological tanks, containing a loading box, an air motor and a distributor equipped with slots expanding from the axis of rotation to the periphery, while the slots are formed by scattering plates attached coaxially to the axis of rotation, and collectively form a circle. The end faces of the diffuser plates have limiters vertically located relative to the plane of the diffuser plate. Limiters ensure that particles of the feed material directly enter the slots and prevent uneven spread of the feed material over the surface. The number of diffusion plates in the distributor can be from 2 to 12, preferably from 6 to 10, respectively, the angle between them decreases with increasing number of plates.

In the proposed boot device, the number of distributors with a set of scattering plates can also be increased, while the distributors are mounted one above the other and are rotatable relative to each other. The number of distributors in the loading device can be from 1 to 2. This is necessary for quick and technological change in the size of the slots between the scattering plates when changing the particle diameter of the loaded material.

The device provides for the possibility of ensuring the same density of the loaded layer in technological tanks having different diameters and heights. This possibility is provided by controlling the speed of rotation of the scattering plates, which in turn depends on the magnitude of the gas pressure supplied to the engine of the loading device. The number of engine revolutions is fixed using a rotation sensor located on the rotor shaft and attached by means of a ring with magnets.

The essence of the proposed utility model is that the diffuser plates with stops attached to the rotor coaxially, made with the possibility of regulating the size of the slots, which are formed using the same plates and together forming a circle, provide a more uniform and dense packing of the loaded layer, as the cross section of the technological capacity, and its height. At the same time, the quality of the stacked layer increases: it is uniform, flat, without “hills”. The same density of the loaded layer, in particular the catalyst, provides a uniform distribution of flows within the reactor, and as a result, better work, while the productivity of the loading device remains constant throughout the entire cycle of the device.

The presence of vertically oriented limiters at the end ends ensures that particles of the loaded material enter the slots between the scattering plates and prevent their accumulation on the periphery of the loaded technological tank.

Figure 1 shows a General view and a bottom view of the proposed device for a compacted loading of bulk materials.

A device for compacted loading of bulk materials consists of a receiving box 1, a pneumatic motor 2, a distributor with a set of diffusion plates with limiters 3, a distributor with a set of diffusion plates without limiters 3a, vertical stops 4, slots formed by diffusion plates 5.

The proposed device for compacted loading of bulk materials works as follows. The feed material is fed into the receiving box 1, then to the distributors with diffuser plates 3 and 4, which rotate using an air motor 2. Figure 2 shows the implementation of the device with two distributors. The feed material, passing through the slots 5 formed by the scattering plates, twists and falls down onto the stacked layer. The density of the layer during the entire load is the same both in the cross section of the apparatus and in height, and the surface is flat, without “hills”. Depending on the height and diameter of the loaded technological capacity, the speed of rotation of the distributor with diffuser plates may vary. When the particle size of the loaded material changes, the size of the slots 5 changes.

The use of the proposed device for compacted loading of bulk materials allowed to increase the productivity of the device, reduce the complexity of its maintenance and, in general, increase the quality of the reactor.
